Genesis 22:3

22:3 Early in the morning Abraham got up and saddled his donkey. He took two of his young servants with him, along with his son Isaac. When he had cut the wood for the burnt offering, he started out for the place God had spoken to him about.

Genesis 24:14

24:14 I will say to a young woman, ‘Please lower your jar so I may drink.’ May the one you have chosen for your servant Isaac reply, ‘Drink, and I’ll give your camels water too.’ In this way I will know that you have been faithful to my master.”

Genesis 31:42

31:42 If the God of my father – the God of Abraham, the one whom Isaac fears – had not been with me, you would certainly have sent me away empty-handed! But God saw how I was oppressed and how hard I worked, and he rebuked you last night.”
